Show HN: HN Favourite Users (chrome extension)

I've made a simple Chrome extension for Hacker News: https://chrome.google.com/webstore/detail/hn-favourite-users/hleiemhnepoghplnnhkhpnjeiaifnobo

It allows you to add your favourite users to a list, and the extension will highlight them here on HN. Simple, but it prevents me from missing comments made by my friends :)

The extension is also open source so feel free to fork it: https://github.com/janhancic/hn-favourite-users

I'll appreciate any feedback you can give me.

Cheers!
